3 LSA 43.2 / Pole SPECIALLY ADAPTED FOR SINGLE PHASE Dedicated single phase alternators have been designed for producing single phase current more competitivly (from 10 to 40%) than reconnected three phase alternators. COMPLIANT WITH INTERNATIONAL STANDARDS The LSA 42.2/43.2/44.2 alternators conforms to the main international standards and regulations: - IEC 0034, NEMA MG 1.22, ISO , CSA / UL on request, marine regulations, etc. It can be integrated into a CE marked generator. The LSA 42.2/43.2/44.2 are designed, manufactured and marketed in an ISO 9001 environment and ISO TOP OF THE RANGE ELECTRICAL PERFORMANCE Class H insulation. Standard 4-wire re-connectable. Dedicated single phase windings, type M or M1, optimised for frequency 0Hz, voltage 240V and PF = 1 (15% derating for use at PF = 0.8) (PF = 1 corresponds to general use for single phase voltage). 4 lead stator allowing the reconnections bellow: - 50 Hz : 230 V in series, 115 V in parallel, - 0 Hz : 240 V in series, 1 V in parallel (excepted for LSA 44.2 : only series). Total harmonic content < 4%. R 791 interference suppression conforming to standard EN group 1 class B standard for European zone (CE marking). REINFORCED MECHANICAL STRUCTURE USING FINITE ELEMENT MODELLING Compact and rigid assembly to better withstand generator vibrations. Steel frame. Cast iron (LSA 43.2/44.2) flanges and shields. Twin-bearing and single-bearing versions designed to be suitable for engines on the market. Half-key balancing. Greased for life bearings (regreasable bearings optional). EXCITATION AND REGULATION SYSTEM SUITED TO THE APPLICATION Voltage regulator accuracy +/- 0.5%.
